fix: always normalize ssa when priting at least one pass

[asterite]

Description

Problem

If you used --show-ssa-pass it would sometimes crash depending on the program.

Resolves #7235

Summary

I'm not sure why that is the case, but it works fine with --show-ssa which normalized the SSA after every pass. As a quick fix, we now also always normalize the SSA after every pass, but we just print the relevant pass(es) if we are told to do so.

Is this related to #7235 in any way?

Looks like a benign change to me 👍
It would certainly explain why I also experienced problems when printing one pass, but not when all of them are printed, good thinking!

It does seem to resolve #7235, though to be honest I don't know why. Maybe there's a bug when normalizing... though I don't understand why it only happens if we normalize once and not always.

In any case this makes debugging easier for the time being...
